含水库城市供水系统的优化调度算法

OPTIMAL DISTRIBUTION ALGORITHM OF URBAN WATER SUPPLY SYSTEM WITH RESERVOIRS

本文建立了含水库城市供水系统优化调度问题的数学模型。根据大系统分解—协调优化方法的基本原理,文中提出了一种按时间分解求解该问题的分解—协调优化算法。其子问题是一个非线性的优化问题,基于Kubn—Tucker的最优性必要条件,文中提出了一种通过迭代计算求解子问题的方法。对该算法利用计算机进行了仿真计算,获得了满意的结果。

This paper builds up the mathematical model of the optimal distribution problem of urban wa- ter supply system with reservoirs. Based on the principle of the decomposition-coordination of large scale systems,a decomposition-coordination optimization algorithm with the time decompe- sition is proposed to solve this problem in the paper. The subproblems are nonlinear. An iterative calculation method is proposed to solve them with the Kuhn-Tucker's optimality necessary condi- tions. The algorithm bas been simulated by computer,and the satisfactory results are obtained.
